Solution Overview

Problem

In networking systems, multiple radios simultaneously scanning the same channel lead to resource wastage, inefficiency, and service disruptions, as they may miss anomalies until the next scan and cause interruptions to clients.

Innovation Solution

A controller identifies a first scan time for multiple radios and adjusts it to determine a second scan time, coordinating channel scanning to prevent simultaneous scanning on the same channel, thereby optimizing resource usage and response times.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple radios simultaneously scan the same channel, then channel monitoring coverage is improved, but resource wastage and system efficiency deteriorate

Engineering Contradiction:
Improvechannel monitoring coverageVSAvoidsystem efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent segments the channel scanning function by assigning different time slots to different radios. The controller divides the scanning task so that each radio scans specific channels at different times, ensuring complete channel monitoring coverage while preventing simultaneous scanning of the same channel by multiple radios.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements periodic channel scanning where radios alternate their scanning activities in time slots. The controller coordinates periodic scanning cycles, allowing each radio to scan channels at scheduled intervals rather than continuously simultaneously, thus maintaining monitoring effectiveness while reducing resource conflicts.

Inventive Principle:
Principle #19Periodic action

2Measurement precision

If multiple radios simultaneously scan the same channel, then detection capability is improved, but response time to anomalies deteriorates

Engineering Contradiction:
Improvedetection capabilityVSAvoidresponse time to anomalies
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The controller performs preliminary coordination by calculating and distributing optimized scan schedules to radios before scanning begins. This preliminary action ensures that radios are positioned to detect anomalies efficiently in their assigned time slots, maintaining high detection capability while avoiding time-wasting conflicts.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements feedback mechanisms where radios report their scanning status and detected anomalies to the controller. The controller uses this feedback to dynamically adjust scan schedules and coordinate responses, ensuring that anomaly detection is maintained while response times are optimized based on real-time system state.

Inventive Principle:
Principle #23Feedback

3Reliability

If multiple radios simultaneously scan the same channel, then scanning thoroughness is improved, but service continuity deteriorates

Engineering Contradiction:
Improvescanning thoroughnessVSAvoidservice continuity
Core Design Contradiction:
ReliabilityVSStability of the object's composition

Solution Approach 1:

The patent implements dynamic scan scheduling where the controller continuously monitors radio status and channel conditions, then dynamically adjusts scan assignments and time slots. This dynamic coordination ensures thorough scanning is maintained while service continuity is preserved by adapting to changing system conditions and preventing simultaneous scanning conflicts.

Inventive Principle:
Principle #15Dynamics

AI summary

Examples herein disclose preventing multiple radios from simultaneously scanning a same channel. The examples identify a first scan time associated with the multiple radios and determine a second scan time based on the first scan time. The examples prevent the multiple radios from simultaneously scanning the same channel through a coordination of channel scanning of each of the multiple radios based on the second scan time.
